The production department of the newspaper has embarked on a quality improvement effort and has chosen as its first project an issue that relates to the blackness of the newspaper print. Each day a determination needs to be made concerning how "black" the newspaper is printed. This is measured on a standard scale in which the target value is 1.0. Data collected over the past year indicates that the blackness is normally distributed with an average of 1.005 and a standard deviation of 0.10.
Suppose that the average blackness of today's sample of 25 spots is 0.952. What conclusion would you draw about the blackness of the newspaper based on this result ? Explain.
